An interesting article at Ars Technica takes a look at some compelling data (the longer-than-normal processor update cycles in Apple's personal computer lineup) and speculates that Apple's enthusiasm for its partnership with Intel might be cooling. Like Apple's soured relationship with once-BFF Google, this may be the result of Intel's increasing activities in the mobile computing space.

If AMD goes out of business, goes private, or gets acquired, then all AMD patents belong to Intel and possible buyer of AMD (in case of acquisition) loses right to produce and design x86 compatible chips.

Apple buying AMD would be favor to Intel and Apple would be left with nothing; they would need to produce new ground up design which is not x86 and not infringe any of AMDs's own patents. Basically to reinvent a company.

Not to mention that it would be a disaster for CPU industry, and would leave everything to Intel.
